Help finding part number for window seal gasket

[Dev680]

Hey all, I have a 2008 128i I’m currently working on, and am trying to locate the right part for the rubber window seal which goes in between the door and the window. Originally wanted to just find a parts car to take out the guesswork but been having difficulty finding one. I believe it’s this however I wanted to make sure as it’s been difficult confirming the right part. Also it’s for the driver side

Please let me know if this is the right part as I don’t want to order the wrong one accidentally! Also if anyone’s replaced this before if I could get any tips or a way I could get it cheaper it’d be a great help. Thanks all
